expensive device for said purpose. This object and features of myinvention are hereinafter fully set forth, reference being had tothefaccompanying drawing, in which,-

Fig. 1 is a top view of my device including a gage clip used on itsfront end when filling vertical seams of walls. Y Y

Fig. 2 is a side elevation of Fig. 1 and Fig. 3 is a front end elevationof the device.

Fig. 4 is a side elevation ofthe device in upright position and its rearpart expanded or spread open for the purpose of pouring a quantity ofmortar into it. Y

Fig. 5 is a perspective view of the gage clip 25 of my device. l

Fig. 6 is a face viewof a position of a brick wall showing the seams tobe filled or finished with my improved device. l

Referring to the drawing by reference numerals, my device comprises anelongated back or base board 10 and a corresponding but shorter pressureboard 11 andvbetween said two boards is provided, on three sides, frontand two opposite sides, a continuous flexible wall 12 with correspondingflanged edges 12E suitably fixed to the side edges of the adjacent facesof said boards and to the front edge part of board 1l (see Figs. 1, 2, 3and 4).

The lower front part of said wall material 12 is not, however, fixed toboard 10 but forms an inverted U-shaped', forwardly directed openingadapted to be fixed exteriorly of and on the rear part of a flat-mouthedoutlet spout 14-15 by suitablek means such as a metal band 13. The mouthof said spout comprises a transverse opening forward of base 10, saidopening being adjustable for suitable outlet width of mortar desired tofill the seams of a wall and designated as 16.

The spout comprises a sheet metal plate 15 fixed on front end of base 10and having two parallel upright flanges 15F near its opposite sideedges. The other part 14 of the spout has corresponding downward sideflanges 14F (Fig. 3) adapted t0 oscillate each par- 1929. serial No.372,620.

allel and close to a fiange 15F and the means for oscillating member 14comprises a pair of side ,ears 14E each with an aperture for a stud 17to project through, said stud being suitably fixed in base 10. On eachstud 17 55 above its ear 14E is a thumb screw 19 adapted to be adjusteddownwardly against the action of a compression coil spring 18 betweeneach ear and the base 10. Thus it will be readily understood that theopening 16 may be any 60 thickness desired within the limits ofadjustment by the thumb screws 19.

n The flexible wall 12 is preferably a heavy rubberized canvas or othersuitable fabric.

F or afclear understanding of the use yof first been set in uprightposition as in Fig. 4 70 and the boards 10,-11 spread from each other asfar as possible.

After filling in mortar as to level 21, (Fig. 4) the adjacent rear endsof boards 10-11 are pressed toward each other to close the rear end ofthe device and the said end parts may then be clamped together by anysuitable meanssuch as the hinged spring jawclamp22 of shallow U-shapedrarranged to clamp the closed ends of 10-11 as in Fig. 2. The clamp 22is shown hinged to member 11 and mayhave an inward curvature as 22C toengage in a grooved part 10C of base board 10. Obviously when the deviceis partly filled with mortar' and the rear part ofthe device is closedas described the front end of board 11 will be forced to spread awayfrom board 10 (see Fig. 2) because of said mortar therein. The operatorthen grasps the device on both sides, at the middle, with his fingersunder board 10 and his thumbs engaging on top of board 11, then holdingthe spout parallel to a wall seam 23 (as in awall 24) and exertingpressure on board 11 with his thumbs the device actsas a bellows,forcing mortark from the spout into the wall seams filling themas theoperator moves along the seam, assuming such seams to be continuous, as

thoseshown horizontal iny Fig. 6. In apre-` ferred size of my device thespout opening 16 10 Stir is too long for proper filling of verticalseams 23, the latter in brick walls being only about 2 inches long. Mydevice is useful also for such vertical seams, as I have provided aspring sheet-metal clip 25 tor this purpose, said clip being of lJ-shapein cross section and adapted to be slipped on the outlet of my deviceand retained thereon frictionally.

The clip must be of such length as to shut ofi outlet of mortar from thespout except for an opening sutiicient to permit outlet Of mortarsuilicient to till a vertical seam 23 as between two alined bricks, saidopening be ing' as between lines ii-B of Fig. l. In lilling verticalseams as described the device must be held in such position that itselongated spent opening is in Yforti-cal plane.

rI'he operation and construction oit` my device in a preferred form havebeen fully disclosed. It is obvious that a number of details i ofconstruction may be embodied without departing from the scope and spiritof the invention. For example, the closing means for the rear end ot thedevice may comprise other mechanical means, and the thumb screws 19 maybe of such construction as to positively engage and raise or lower thespout section lll as desired without the use of compression springs I8.The main body ot my device is mentioned a bellows structure but used tosqueeze mortar from its normally Widest end while its opposite end isclosed.

I claim:

l. In a mortar filling device of the class described, a pair oielongated normally parallel board members alined at one end and one otsaid members shorter than the other, a metal outlet spout mounted on thelonger board beyond the other end of the adjacent shorter board, saidspout having an outlet transversely ot the board and parallel to andoutwardly oi the forward end of said board, a flexible wall memberconnecting to the adj acent parts ot' said boards at their side edgesand having a. forwardly directed opening arranged to communicate withthe rear part of said spout.

2. The structure specified in claim l, and said Vspout comprising afixed flat plate. part secured on the longer board and an upper partwith a plate parallel to said iixed plate and means for adjusting saidupper plate with relation to the fixed plate for selective amount oi"opening therebetween, and means for shutting oli a portion of saidvariable i opening.

3. The structure specified in claim l, and said spout comprising a iixedflat plate part secured on the longer board and an upper part with aplate parallel to said fixed plate and means for adjusting said upperplate with relation to the ixed plate for selective amount of openingtherebetween, and means for shutting oli a portion of said variableopening Vcomprising a sheet metal clip of predetermined length and ofU-shape in cross section, said clip adapted to be slipped over the spoutopening and trictionally engage same.

e. In a mortar filling device of the class described, a pair otelongated normally parallel board members alined at one end and one ofSaid members shorter than the other, a metal outlet spout mounted on thelonger board beyond the other end of the adjacent shorter board, saidspout having an outlet transversely of the board and parallel to andoutwardly of the forward end ot said board, a fiexible wall memberconnecting to the adjacent parts of said boards at their side edges andhaving a forwardly directed opening arranged to communicate with therear part ot said spout and means for closing the adj acent rear endparts of said board members toward each other and holding them closedfor the purpose set forth. n

5. A mortar joint and seam .filler comprising an elongated rigid basemember, a spout mounted at the :front end thereof and having an outlettransversely ol the said base beyond its front end, an elongatedpressure member shorter than the base member and normally in spacedrelation to the latter and both said members connected with their rearends in common plane with the front end ot the compression member inspaced relation rearwardly of the said spout; means forl holding saidrear end parts clamped toward each other, the means for connecting saidmembers comprising integral flexible side and front walls, said frontwall provided with an outlet part securable to the rearwardly openingpart of said spout, said rear end closing means adapted to be releasedto permit spreading of said base and compression mem bers, for thepurpose described.

In testimony whereof I affix my signature.
